Water Monitoring & Standards Program
Water monitoring, standards & assessment
Collect, analyze, & distribute high quality data and information
Information used by DEP, other state agencies, federal & local governments, environmental community, business community, & general public

Research
Uses of Ambient Water Quality Data
• 305(b) Report (a primary data source)
• 303(d) listing/de-listing process
• Developing waterbody specific TMDL approaches
• Background / reference data utilized in standards development
Freshwater & Biological Monitoring
•Where do we monitor:• Rivers• Streams• Lakes
• What do we monitor:• Water column chemistry• Sediment chemistry• Biological conditions• In-stream & Riparian Habitat
Ambient Surface water monitoring network:
• Cooperative program with USGS - develops chemical / physical data to establish status and trends in water and sediment quality.
–Total of 115 surface water stations
Chemical Monitoring
Parameters Include:- Nutrients- DO- Bacteriological- Metals- Volatile Organics- Pesticides
(2003-2004)
Ambient Ground water monitoring network:
• Cooperative program with USGS and NJGS - develops chemical / physical data to establish status and trends in shallow ground water quality.
–Total of 150 ground water stations
Chemical Monitoring
Groundwater Monitoring Network
- Shallow well network
- 150 wells total
- Land use-based - Agriculture - Undeveloped - Urban
- Parameters monitored:nutrients, VOCs, metals, pesticides, radioactivity
Supplemental Ambient Surface Water Monitoring Network
• Initiated October 2000
• Station siting criteria:– Coverage in all 152 - HUC 11 units– Integrator locations– At AMNET (Biological) sites– Include tidally influenced sites– Stakeholder input
• 177 Sites for 2 Years of Quarterly Sampling
• Parameters - nutrients, flow, and field parameters
Supplemental Ambient Surface Water Monitoring
Network Sites
CY2000 - 2004
Supplemental Ambient Surface Water Monitoring
Network Approach• Quarterly sampling for two years
• Oct. 2000 to Sept. 2002– WMA’s 1, 2, 3, 6, 8, 9, 10, 12, 18 and 19
• Oct. 2002 to Sept. 2004– WMA’s 4, 5, 7, 11, 13, 14, 15, 16, 17 and
20
Biological Monitoring
•Ambient Bio-monitoring Network (AMNET)
•Over 820 stations•Sampled 1x/5yrs•Uses benthic macroinvertebrates as indicators of river/stream aquatic health
•Fish Index of Biotic Integrity (FIBI) •Supplements AMNET•Uses fish number and diversity (variety) as indicators
• Biological Monitoring
–Ambient Biomonitoring Network (AMNET) & Fish Index of Biotic Integrity (FIBI)• Both include semi-quantitative
assessments of in-stream and riparian habitat quality

Ambient Lake Monitoring Network
•Designed to provide the water quality data necessary to assess ecological health.
•200 randomly selected lakes from the ~ 1100 named lakes.
•40 lakes monitored per year, 3 times in a year (Early Spring, Summer & Late Fall)
•Determining status and long-term trends in lake water quality.
Ambient Lake Monitoring Network
•Water quality measurements conducted at each lake include:
•Dissolved oxygen• pH•Temperature•Specific Conductance• Alkalinity• Hardness• Secchi depths•Nutrients, and•Chlorophyll ‘a’
Lakes Selected for Year One of Monitoring
Ambient Lake Monitoring Network
•In addition to this effort to monitor the overall health of our lakes statewide, the state is conducting follow-up monitoring on targeted lakes:
•Seven lakes, for which ambient monitoring data are needed to determine if restoration activities have been effective, will be monitored over the next five years using the same protocols described for the Ambient Lake Monitoring Network.
Targeted Water Quality Monitoring Activities
• Targeted Monitoring (regional & local):– Impaired Waterbodies List
• Elevated Flow Metals Monitoring
– TMDLs• Non-point Source Monitoring (Lower
Delaware Basin)• Statewide Stream Bacteriological TMDL
Source Identification Monitoring • Stream specific TMDL Monitoring (Rancocas
Creek, Shark River, etc.)
Targeted Water Quality Monitoring Activities
• Targeted Monitoring (regional & local):
– Pollution / Impairment Track-down Monitoring
• Mirror Lake Lead contamination
– Automated Water Quality Monitoring• Diurnal DOs in streams
Targeted Water Quality Monitoring Activities
• Targeted Monitoring (regional & local):– Biological Monitoring Refinements
• Pinelands Biometric Development• Northern Region AMNET Genus/Species
Biometric Development• Headwaters Fish IBI Protocol Development
